Facebook is exploring new ways for individual users to profit from their posts on the network, The Verge has learned. A user survey distributed this week hints at a broad range of ways that users could make money or promote a cause, including a tip jar, branded content, and taking a cut of the ad revenue Facebook earns from posts. The survey also asked users to indicate their interest in a "call to action" button, a way to let followers make donations, and a "sponsor marketplace" to match users with advertisers. It's unclear whether Facebook is considering making these options available to all users; the language of the survey indicated it is targeted at verified users. The survey was spotted on the page of a verified user with a relatively small following. (OK it was me.)
